√18

1) Looking at the numbers of that expression


(-10)/(-13.4)\text{ }√(18)+\text{ 22.7777}\ldots

So we have two Rational numbers and one Irrational, the only one that does not belong is, therefore, the Irrational one

Since √18 can't be written as a ratio since 18 is not a perfect square. There is not a rational number as the result of that radical

22.777....can be written as a ratio

And -10/-13.4 can be written as a ratio as well.
